Why have I been seeing this egregiously wrong idea everywhere lately? Delivering power in the form of microwaves to the Earth is not going to cause any warming.

Why have I been seeing this egregiously wrong idea everywhere lately? Delivering power in the form of microwaves to the Earth is not going to cause any warming. Even if we were to purposefully beam it straight into the ocean and heat the water we just aren't capable of delivering enough wattage to make a serious difference. The reason global warming is a concern is because of the greenhouse effect of CO2 trapping the Suns heat which is an energy input that we can't even come close to approximating.
